Most likely they requested permission and received it. I regularly get requests for permission to use my images in all sorts of publications, even though the images are already tagged with free licenses. One time when I mentioned that, I got a reply back saying "yes, we know the image is free, but we always make the request anyway". Granting permission to use promotional images is so routine that we have to phrase our requests for a free-license image carefully, so that they understand that we are asking for far more than simple permission to use.
